Deceptive Phishing Campaign Targets Chrome Extension Developers

A recent phishing campaign has targeted developers of Chrome browser extensions, compromising at least 35 extensions and injecting data-stealing code. This malicious code specifically targeted Facebook account information, including Facebook IDs, access tokens, account information, ad account information, and business accounts.

Here is a summary of the article:

Phishing emails were sent to Chrome extension developers, disguised as emails from Google Chrome Web Store Developer Support.
The emails claimed that the extensions violated Chrome Web Store policies and were at risk of removal.
The emails contained a link that led to a fake login page, designed to steal the developer’s Google account credentials.

Once the attackers had access to the

The compromised extension was then published as a “new” version on the Chrome Web Store.

What Undercode Says:

This phishing campaign highlights the importance of security awareness for developers. Developers should be cautious of any emails that claim their extension is in violation of Chrome Web Store policies. They should also avoid clicking on links in emails and instead navigate to the Chrome Web Store directly.

Here are some additional insights on the blog article:

This attack campaign demonstrates the effectiveness of social engineering tactics. The attackers were able to deceive developers into clicking on a malicious link by posing as legitimate Google representatives.
This campaign also highlights the importance of multi-factor authentication (MFA). While the developer in this case had MFA enabled, it did not prevent the attack because the OAuth authorization flow did not require MFA approval.
This attack specifically targeted Facebook account information, suggesting that the attackers may be interested in compromising Facebook business accounts. Facebook business accounts can be valuable targets for attackers, as they can be used to launch phishing or disinformation campaigns, or to make fraudulent payments.

It is important for developers to be aware of the latest phishing tactics and to take steps to protect themselves. Developers should enable MFA on all of their accounts and avoid clicking on links in emails. They should also be cautious of any emails that claim their extension is in violation of Chrome Web Store policies.
